Call of Duty Modern Warfare 2

I got myself Call of Duty Modern Warfare 2 for Christmas because I wanted to try and go back through on Veteran as well as do some of the special ops stuff, and while I'd love to do both of them, I can't.  I'm too addicted to the multiplayer.  I've never been much of a multiplayer gamer before, but I'm addicted to MW2.  My favorite mode has to be Domination.  It's so much fun to play.  I started out the other day at level 1 and I'm now up to 17 I think.  I found a really good deal on it for PS3, so that's what I'm playing on.  My PSN tag is itsmedave if anyone would like to play.
